Protesters want to be able to communicate, to document the protests, and to share photos and video with the world. So they’ll be carrying phones, and they’ll face a complex set of considerations about the privacy of the data those phones hold. We hope this guide can help answer some questions about how to best protect that data, and what rights protesters have in the face of police demands. (more…)

RALEIGH, N.C. — Police in Raleigh and Durham are using a controversial tool to fight crime.

Commonly called Stingray, the small suitcase-sized technology acts like a cell tower and allows police to track cellphone data. Critics say the devices, which are also in use in Charlotte and Wilmington, invade people’s privacy because they can collect information on the location and activity of cellphones.

“It is a very concerning technology because of its capability, but it’s also concerning because it’s so secretive,” said Sarah Preston, policy director of the American Civil Liberties Union’s North Carolina chapter.

Raleigh police have used Stingray for five years, police department spokesman Jim Sughrue said Monday, but he didn’t provide any other information regarding use of the device. (more…)

All across America, from Florida to Colorado and back again, the country’s increasingly militarized local police forces are using a secretive technology to vacuum up cellphone data from entire neighborhoods – including from people inside their own homes – almost always without a warrant. This week, numerous investigations by major news agencies revealed the US government is now taking unbelievable measures to make sure you never find out about it. But a landmark court ruling for privacy could soon force the cops to stop, even as the Obama administration fights to keep its latest tool for mass surveillance a secret.

So-called International Mobile Subscriber Identity (IMSI) catchers – more often called their popular brand name, “Stingray” – have long been the talk of the civil liberties crowd, for the indiscriminate and invasive way these roving devices conduct surveillance. Essentially, Stingrays act as fake cellphone towers (usually mounted in a mobile police truck) that police can point toward any given area and force every phone in the area to connect to it. So even if you’re not making a call, police can find out who you’ve been calling, and for how long, as well as your precise location. As Nathan Freed Wessler of the ACLU explained on Thursday, “In one Florida case, a police officer explained in court that he ‘quite literally stood in front of every door and window’ with his stingray to track the phones inside a large apartment complex.”

Yet these mass surveillance devices have largely stayed out of the public eye, thanks to the federal government and local police refusing to disclose they’re using them in the first place – sometimes, shockingly, even to judges. As the Associated Press reported this week, the Obama administration has been telling local cops to keep information on Stingrays secret from members of the news media, even when it seems like local public records laws would mandate their disclosure.
